Renewed March 24, 1933 Claims.

YThis invention relates to a drawer of lniockdown readily assembled forman which, when assembled, is greatly strengthened and reiniorced at itscorners by reason of the nietal connecting members utilized at thecorners for tying the side and end members oi the drawer together andfor holding them against disarrangeinent or separation.

The present invention is primarily concerned with an exceedingly simpleand. practical construction of drawer, wherein the parte thereofA arevery readily and easily machined and in which the assembly may beaccomplished in the factory or at the place of shipment of the articleof furniture in which the drawers are to be installed. The invention isdirected to a novel, economical and practical structure for attainingthe ends stated, at the saine time e'ecting a very materialstrengthening and reinforcing of the drawer structure.

An understanding of the invention may be had iron/1 the followingdescription, taken in connection with the accompanying drawing, inwhich,

Fig. 1 is a perspective view of a drawer made in accordance with myinvention.

Fig. 2 is a perspective view o a corner made in accordance with myinvention.

Fig. 3 is a raginentary perspective view showthe formation at the endsci the sides and ends of the drawer with which the corner tie membershown is used.

Fig. l is a fragmentary horizontal section through one corner of adrawer after the parts have been assembled, and Y Fig. 5 is aperspective View showing a different form of metallic tie constructionwhich may be used in the place oi that shown in Fig. 2.

Like re erence characters refer to like parts in the diierent figures ofthe drawing.

The drawer includes the usual vertical sides l, and ends 2 which, attheir inner sides near their lower edges, are horizontally grooved,making grooves 3 for the reception or" the side and end ed es of abottoni 4 which is held in place 'hen the two sides and two ends of thedrawer are connected together.

Each end 2 of the drawer is of greater thickness than the sides l, andeach end at its inner side and at each end is cut away making a rightVangle vertical recess 5; and in line with the vertical sides oi saidrecess, narrow grooves 6 andv 7 are cut, as shown in Fig. 3, which lieat right angles to each other. It is evident that in sawing the endmember 2 of the drawer to remove the Ymaterial in making the right anglerecess 5,

a continuation oi the saw cuts beyond where they meet provides thegrooves 6 and 7.

Each side l at each end thereof and at its inner side is provided with avertical groove 8 which lies substantially in the samev plane with theinner side oi the adjacent end 2 oi the drawer when the partsvareassembled. In addition` each oi the side members l oi the drawer at itsouter side and at each end has a vertical rabbet 9 made therein, thedepth oi which is the same as the thickness oil the metal from which thetie inembers used at the corners are made. Likewise the Luth of thegrooves 6, l and 8 are substantially in, saine as the thickness of suchmetal.

The instal tie rneinbeil used at eachV corner oi the drawer may be thatillustrated in Fig. 2. As there shown a length oi nat metal is bentlongitudinally to 'provide two legs l0 and l1` at right angles to eachother, the free edge portions of which are each turned at right anglesto make vertical terminal lips 12. One of the legs, such l0 of themember, near the lower end Ythereof. has a notch i3 out away so designedthat the upper side of the notch will. come against the upper side olthe drawer bottoni 4 when the tie` member is inserted and driven inplace. At the vertical corner, where the legs 10 ll join, tongues 14 andl5, respectively are struckY from the legs l1 and l0, respectively, and,are in posi? tion in the planes oi' said legs l0 and l1. Each of thesetongues at its outer freevertieal edge is cut'downwardly and inwardly,indicated'at i5, making each tongue in effect a' tooth which ireelypermits the downward movement ofthe tie uiernber into place, but whichwill bite or gouge into the wood from which the sides and ends land 2are made to prevent any upward movement yci such tie member after it hasbeen inserted.

The assembly of the sides and ends and bottoin is simple. The bottomhaving been located in the grooves 3, at each corner of the drawer oneof the metal tie members illustrated in Eig. 2 is inserted downwardly,the flanges l2 entering the groove 8 and the rabbet 9 and the tonguesifi and l5 entering the grooves 6 and 7, while the leg lo lies betweenone side of the recess 5 and the inner side of the side l of the drawer,and leg 11 between the other side of the recess 5 and the vertical endofthe drawer, all as fully shown in 1Eig. e. And once the tie member atthe corner is in place the toothed tongues 14 and 15 prevent disassemblyas described.

A different form of metallic tie construction may be used, like thatshown in Fig. 5. It consists of two members, each made of ilat metalinto Z-bar form, having a web 17 and flanges 18 and 19 turned inopposite directions from the opposed vertical edges of the web. Each ofthe webs 17 is also provided with inwardly struck retaining tongues 20,and at a lower corner of one of the members a notch 13a is made for thesame purpose as the notch 13 in the construction illustrated in Fig. 2.

This construction is used in substantially the same manner, the flanges18 being equivalent to the lips 12 previously described, the webs 17equivalent to the lips l2 previously described, and the flanges 19equivalent to the tongues 14 and l5 except for the toothed retainingfeature applicable to the tongues, which, in the structure shown in Fig.5, is taken care of by the retaining tongues 20.

With this construction the parts, including the sides, ends and bottomof a drawer, may be fabricated in large quantity production and themetallic tie members separately produced. The drawers which are to beused, may be assembled after they have reached their destination. The

assembly is made readily without the use of skilled labor and the drawerproduced is one very much strengthened and reinforced at the cornerswhere the vertical metallic tie members are located. The invention isdeiined in the appended claims and is to be considered comprehensive ofall forms of structure coming within their scope.
